# 
# Given the array `nums` consisting of `2n` elements in the form
# `[x1,x2,...,xn,y1,y2,...,yn]`.
# 
# _Return the array in the form_ `[x1,y1,x2,y2,...,xn,yn]`.
# 
# 
# 
# **Example 1:**
# 
#     
#     
#     Input: nums = [2,5,1,3,4,7], n = 3
#     Output: [2,3,5,4,1,7] 
#     Explanation: Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is [2,3,5,4,1,7].
#     
# 
# **Example 2:**
# 
#     
#     
#     Input: nums = [1,2,3,4,4,3,2,1], n = 4
#     Output: [1,4,2,3,3,2,4,1]
#     
# 
# **Example 3:**
# 
#     
#     
#     Input: nums = [1,1,2,2], n = 2
#     Output: [1,2,1,2]
#     
# 
# 
# 
# **Constraints:**
# 
#   * `1 <= n <= 500`
#   * `nums.length == 2n`
#   * `1 <= nums[i] <= 10^3`
